Abstract: AIRCRAFT PROPULSION SYSTEM           WITH FLIGHT MANEUVERABLE EXHAUST NOZZLE                    Abstract of the Disclosure An aircraft propulsion system is provided which incorporates a flight maneuverable exhaust nozzle. In one embodiment, gas turbine engines are mounted on both sides of an aircraft fuselage, each engine having an exhaust duct partially defining an exhaust stream flow path. The duct transits from a substantially cylindrical diffuser section aft of the engine to a relatively high aspect ratio section proximate the trailing edge of the wing. Exhaust gases are expelled through a thrust vectorable nozzle which is conto?? within the wing and which is adapted to increase wing lift through the concept of supercirculation. Maximum aerodynamic advantage is achieved by distributing the exhaust flow over a significant portion of the wing span at the trailing edge. Thrust augmentation is provided by means of a long, flat duct burner disposed within the high aspect ratio section proximate the exhaust nozzle thereby minimizing turning losses and cooling air requirements.         The exhaust nozzle includes an articulated deflector partially defining both the exhaust stream flow path and the wing upper surface.          Synchronous movement of the two flaps comprising the deflector ensures proper internal area control prior to exhaust gas vectoring. The nozzle throat area is varied by a lower flap disposed in general opposition to the articulated deflector. Actuation means are provided to vary the throat area and produce the proper thrust vector angle by positioning the lower flap and articulated deflector, respectively.

Abstract: A?TRACT OF THE DISCLOSURE            The disclosure is directed to apparatus for folding processed fabric.  It is particularly useful for, although not necessarily limited to, the folding of processed tubular knitted fabric.  The folder is positioned at the discharge end of a fabric processing line, and is arranged to convey the fabric, moving at relatively high speed, to a discharge point directly above a folding platform.  The fabric is then directed downward between guides, which oscillate back and forth over the folding platform, to lay the fabric in successive layers of substantially uniform length.  The construction of the oscillating guide member accommodates passage of the fabric downward at relatively high speeds while the oscillating guide is moving forward and backward at relatively high speed.  The guide is constructed of opposed, relatively large panels, extending across the full width of she fabric and forming a gradually converging path, leading to dis-charge rollers at the lower end of the folding guide.  The panels are air permeable over their entire working areas, so as to provide for a general but low velocity flow of air outward from the face of the panel.  This serves to provide a cushion, minimizing contact between the fabric and the rapidly oscillating guide panels, such that the downward movement of the fabric is uninhibited.

Abstract: MAGNETIZING CURRENT SWITCH     ABSTRACT OF THE DISCLOSURE         A magnetizing current switch particularly adaptable for use in gas insulated substations comprising a sealed housing including two spaced-apart electrical conductors and a movable contact for electrically connecting or disconnect-ing the electrical conductors.  A rotatable drive shaft is coupled to drive means, which translate the rotation of the drive shaft to a generally straight-line motion, and the straight-line motion moves an insulating rod which is secured to the contact, thereby positioning the contact either in contact with both conductors, or spaced apart from at least one of them.   The drive means includes a pair of support members and a pair of spaced-apart pivot links pivotally coupled to the support members.  One of the pivot links is coupled to the drive shaft, and a link connector couples the pivot links together.  The link connector can rotate within the pivot link openings provided therein, and upon pivotal movement of the pivot links, the link connector experiences both an arcuate and a rotational movement.  Spaced-apart drive arms fixedly secured to the link connector cooperate with the insulating rod, and upon the arcuate and rotational movements of the link connector, the free end of the drive arm traverses a substantially straight line, thereby moving the insulating rod and the movable contact.

Abstract: SAFETY LATCH FOR AUTOMOTIVE HOISTS            Abstract of the Disclosure A safety latch preventing inadvertent lowering or dropping of an automotive hoist by means of a torsionally biased pawl shaft that automatically self engages with a lateral notch located in the lift at hoist operating height.  The backside of a vertically movable gear rack attached to the hoist includes the pawl notch near its lower end and which when raised cooperates with the pawl shaft for effecting a latching relation therewith.  The pawl shaft is slotted to embrace the gear rack and is manually releasable for permitting hoist descent by a partial rotation which in one embodi-ment is effected by manually shifting a bi-stable locking rod.          Reset for latching on subsequent ascent of the gear rack is effect-ed by descending engagement of the hoist bolster against the bi-stable locking rod.  In an alternative embodiment release is ob-tained by raising a lift pin which similarly effects partial rota-tion of the biased pawl shaft.  An auxiliary latch in the alterna-tive embodiment prevents self-reset of the pawl shaft until after the notch descends a distance beyond which the pawl shaft and notch could otherwise relatch.     1a

Abstract: GRAIN STIRRING APPARATUS AND METHOD          Abstract of the Disclosure An apparatus and method are provided for effec-tively moving and stirring grain in a storage bin.  The apparatus comprises a sweep arm, including an auger support shaft and an independently rotatable drive member, that extends between and is supported on a track along the bin sidewall and a pivotal support at the bin center.  As the drive member is rotated, a drive wheel thereon moves over the bin track, causing the sweep arm to travel around the bin.  The support shaft is rotatable independently of the drive member and extends from the central frame to a loca-tion adjacent the bin track.  A plurality of spaced stirring augers depend from the laterally extending support shaft, and all except the outermost one are adapted for movement therealong.  Rotation of the support shaft in either direc-tion will cause corresponding movement of the movable stir-ring augers along the sweep arm.  The outer auger remains near the outer wall of the bin.  Movement of the stirring augers along the sweep arm, and of the sweep arm around the bin will result in an effective grain stirring path.
